Abstract
Aims: A large genome-wide analyses of UK Biobank data reported 15 novel loci associated with the susceptibility of hip osteoarthritis (HOA). We aimed to replicate the association of these loci with HOA in the Chinese population.Methods: A total of 13 Single Nucleotide Polymorphisms were genotyped in 892 HOA patients and 1123 healthy controls.Results: The risk allele frequency of rs62578127 and rs11059094 was significantly higher in the patients than in the controls. The mRNA expression of LMX1B (p = 0.01) and MLXIP (p = 0.001) were significantly increased in HOA tissues.Conclusion: We successfully replicated two novel susceptible loci of HOA and further characterized two potential causative genes.
